Title: Improvements in and relating to prepayment devices for quantity meters
IPC: G07F15/04
Filed: 1928-11-30
Abstract: 328,655. Small, F. G. Nov. 30, 1928. Divided on 325,853. Gas, supplying by meter.-In a quantity meter prepayment mechanism in which the cam 2 operating the valve controlling the fluid flow is secured to an arm 9 carrying a planet wheel 6 which engages sun wheel 10 operable on the insertion of a coin to open the valve and an internally toothed wheel 8 operated through worm gearing 3, 4 to close the valve by the passage of the fluid, means are. provided to prevent the driving member 7 on the coin pocket from being moved into engagement with a ratchet wheel 5 to turn the sunwheel 10 when after the insertion of a predetermined number of coins the cam is nearing its end position. These means comprise a plate 27 on a sleeve 26 normally pressed by a spring 30 against a stop 31 on one end of a spindle 25 which is axially slidable in the hub 11 of the wheel 10 and ratchet wheel 5. The spindle 25 carries at its other end a cup 24 fitted with a pin 22 which is guided by a forked arm 32 and engages a helical groove 21 of varying pitch in a sleeve 20 rigidly connected to the cam 2. When after a predetermined prepayment the cam approaches its end position the engagement of the pin 22 with the groove 21 causes the spindle 25 to be moved to the right and the plate 27 presses against the side of the member 7 thereby compressing the spring 30. When the last inserted coin is discharged the member 7 moves radially outwards and the plate 27 moves under it so as to prevent its further operation until a certain quantity of gas has been consumed. Indicators. - The amount of unconsumed gas is indicated by a pointer 14 on a spindle 15 carrying a toothed are 16 engaging a pinion 17 rigidly connected to the arm 9.

Title: Photoprinting device and method
Inventor: JR CLIFFORD ERNEST HERRICK
IPC: G03B27/20
Filed: 1961-02-07
Abstract: 912,100. Photocopying apparatus. GENERAL ANILINE & FILM CORPORATION. Feb. 7, 1961 [March 1, 1960], No. 4571/61. Class 98 (2). In a reflex photocopying device, the original and a light-sensitive element are placed in superposed position within an airtight casing having collapsible walls and an expansible lighttransmitting member, and the air evacuated from within the casing, so that the walls are collapsed, and the light-transmitting member expanded to hold the original and copy sheet in intimate contact while the exposure is made. In Fig. 2 the casing 10 is formed of rubber, and exhausted through a valve 12. The original to be copied is shown as an open book 20, the lightsensitive copy sheet 21 and an optional screen 22 being positioned above these, as shown. The upper end of casing 10 is closed by a rigid transparent plate 14 and an expansible air-impervious transparent sheet 15, suitably of plastic material. When casing 10 is evacuated, the walls collapse as shown in Fig. 3, and the pressure of the air between plate 14 and sheet 15 causes the latter to expand so as to force the copy sheet 21 into intimate contact with the open book, as shown. (This pressure can be adjusted by a valve 17.) The exposure is then made by a bank of fluorescent tubes close to the plate 14. In the modification of Figs. 5 and 6, (not shown) the sheet 15 is replaced by a closed air-tight bag of similar material placed loosely on top of screen 22 and copy sheet 21. In the further modification of Fig. 7, the upper open end of casing 10<SP>1</SP>, which is similar to casing 10, is secured to a frame 25. Hinged to frame 25 is another frame 27, to which is secured a taut sheet 28 similar to sheet 15. The two frames are closed together to form an air-tight chamber, which is then exhausted through valve 26, so that sheet 28 is driven inwards by atmospheric pressure to act as in the previous examples. Specification 889,363 and U.S.A. Specification 2,591,449 is referred to.

Title: Improvements relating to stabilised dc power supplies

IPC: G05F1/573
Filed: 1961-02-10
Abstract: 946,986. Automatic voltage control. SOLARTRON ELECTRONIC GROUP Ltd. Feb. 12, 1962 [ Feb. 10, 1961], No. 5089/61. Heading G3R. [ Also in Division H3] A voltage regulator of the series transistor type has output terminals 01, 02 and derives its input from a transformer T1 over a rectifying and smoothing circuit RS1, the output being stabilized in known manner by three series connected transistors X1, X2 and X3. The base of transistor X3 receives the error signal amplified over transistor X4 and derived from a potential divider R20, RV1 and R21, transistors X5 and X6 and a reference Zener diode MR13. The current through the series resistors is limited to a permissible level by limiting the voltage on the collector of transistor X5 by means of a transistor X7, the emitter of X7 being connected to the collector of X5, the voltage on the emitter of X7 being limited at the voltage of the base thereof by a network R15, R16, R17. An amplifying transistor X8 also controls the level of limiting by varying the base voltage of X7, the arrangement being such that when the load current increases slightly above a predetermined level limiter X7 comes into play and current remains steady over a short range of load resistance; a further reduction in load resistance causes transistor X8 to conduct reducing the limiting level and causing the current to fall linearly with decreasing load resistance. Zener diodes MR9, MR10 and MR11 are connected across X1, X2 and X3 to protect these transistors against over-voltages. An arrangement including ganged switches S1, S2 and a forwardly conducting diode MR1 is provided to compensate for the contact resistance of the usual output isolating switch S1, which contact resistance would normally result in the voltage across the output terminals differing slightly from the voltage across the potential divider R20, RV1, R21.
